Application filed. May 28, 1928. Serial No. 281,093.

This invention relates to a fish cleaning machine.

An object of the present invention is to provide a fish cleaning machinewith a means for conveying an entrail removing member in synchronismwith the motion of a con veyor which holds the fish to be cleaned, so

that the machine is capable of continuous and uninterrupted operation.The machines 10 heretofore employed for cleaning fish have generallyrequired the use of entrail removing means which do not penetrate intothe visceral cavity of the fish or have required that the fish holdingmeans be subjected to a step by step motion in order that the fishholding means be stationary during the op erations of the entrailremoving member.

WVhen the entrail removing member does not properly enter the visceralcavity of the fish, the cleaning operation is imperfect. When the fishholding means must be stopped each time the entrail removing memberoperates upon the fish, the capacity of the machine is very low. Thepresent invention provides a means by which the fish may be completelycleaned in a machine having a large capacity.

A further object of the present invention is to provide a fish cleaningmachine in which the entrail removing member or members are constructedto enter properly the visceral cavity of the fish, even when the fishare presented in different positions near the entrail removing member.By a machine of the present invention, it is unnecessary to accuratelyposition fish in a predetermined position in the fish holding members ofthe machine. This permits the machine to be fed by mechanical means orin case of manual feeding of the machine, simplifies this feeding.

Another object of the present invention is to provide a fish cleaningmachine with a fish holding conveyor and with an improved form of beltoperative for holding the fish in the conveyor during the cleaningoperations.

Various further objects and advantages of the invention will be foundmore fully described from a description of a preferred form orexample ofa fish cleaning machine embodying the invention.

For this purpose, there is hereafter described With reference to theaccompanying drawings, one form or example of a machine embodying thepresent invention.

Referring to the drawings: The fish cleaning machine is illustrated ascomprising, as

front end view ofthe eni major elements, a conveyor 2 for holding 7 thefish to be cleaned,"two pairs of disc knives 3, a-and'o, 6 positioned tooperate at opposite sides of theconveyor for removal of the heads andtails of the fish and 'a plurality of entrail removing members 7 mountedby means, such as a turret 8 for conveying the entrail movlng memberstogether with the movement of the conveyor 2 so that the entrailmovingmembersmay operate upon the fish while the fish are beingcontinuously moved by the conveyor 2.

The conveyor 2 is formed with a plurality of fish receiving or holdingmember 9, preferably of the size to receive a single fish of the kindoperated upon. The conveyor 2 is mounted to travel around the sprockets10 and 11 mounted upon shafts12'andv13' respectively. The shafts .12 and13 are journaled' in the frame '14 oft-he machine which is here shown'tobe made of angle iron. The shaft 12 is journaled in adjustable bearingbracket 15 adapted to be adjusted ffor properly .tighteningjthe I conve;or 2. Mounted upon the shaft 12 is an a diiien spmkstwhee 16 w i d i 'pi ta n-vee we t th dof which passes aroma a sprocket wheel 19 journalednear the front center of the frame. The conveyor 17 is provided withholding members or cups 18 which support the head of the fish whichoverhangs the fish .holders 9 of the conveyor 2-before these heads aresevered from the fish. Theconveyor 17 thus provides a means foripreventing the fish "from sliding out of the "conveyor 2.

The fish, cleaning machine alsoincludes a belt 20 which'serv'es as ameansgfor holdin; the fish within the-fish receiving members 9 duringthe operations of ciitting the heads, andjtails *from-the'fish. Thebelt20, is preferably 1 constructed. of wire mesh and is shown as having itsbottom portion "spaced slightly above the top of the conveyor 2 andparallel :with :it, belt 20 passes over rollrs 2l -aiid-22 suitablyournaled in "the frame 14 of the"machine -and "also passesover a "belt"driving member 23. The belt 22 is preferably journal'edrin'abracket-27:havingr azyiel'ding support from thebracket .28, fixed-*to 'the frame"1 1 to p rovide-an additional means for a plying-;the pressure foritighteniiigrthe 'be' t "20. There is *also :provided'a :gui'de -29 "forthe belt "20, supported by "the frame ('14 from *a bracket 30. {There:is also :provided an additional fish holding belt -31-icovering thefish in the i conveyor2 throughout: that portion of the .yarmeans:forfapplying tension "to the rear -cco nveyor'-"'atv which the fish intheconveyor fare operated; upon 'by the -entrail remov- :ingmembers 7.The belt=-31 bein gtrained .over the curvedrportibnbf the conveyor atthe-rear end i'of the machine. For-this'purwpose, .:the belt '31 isindicated 5' as :passing jaround a'roller32 above the conveyornear therear-endfa roller-33 below the conveyor :ne'ar-the rear-enii,-and""arearroller 34: which is:rlhistra'ted "as mounteiol in a "bracket 35,gjyieldi'ngly supported at vth'e rear end'jofthe frame -14,=so that jthe roller 34* operates as -belt:3'1 'Thebe-lt:31"is alsoxpreferably compose'd of ;wire *mesh a'ndisiprovfded with a ;-nu1'nber of-rods "36oriotherrneans-by which the belt 31 :'may-be "driven inaccurate syn-Iheads and tails of *the-fi-sh outwardly hereinafter pointed out inconnection with the description of the turret 8.

The shaft2 l which mounts the forward fish holding belt -20, alsojmounts the upper clitting discs *4: and The lower "cutting discs 3 and5 of the machine aresiipported upzsaashaa 37, journaled to the frame 14and the discs stand 6, adjacent the fish receiving members!) of theconveyor 2, there by providing means by which the head fand "tail of thefish may be readily severed as the fishare conveyed by the meeting-edgesof the knives '3, 5, 4, "and6 (see Fig. 9). Below the'knives 3 and;5,there is indicated baffle plates 38 and 39 for discharging the fromthe center of the machine. y

For driving the parts of the mac'hine hereinbefore describfcchabelt=pulley 10 'is V journaled on a shaft Mat-the top of the framell;and said shaft 41 carries, at the side. of the frame, a sprocket 42,around which is trained a driven cl'iain 43 which passes around-asprocket 14C on-the shaft37 chain 43 also-p asses around af chaintightenroller 47 mounted bybracket-{l8,-having a yielding connectionwith the frame -14.

There are thus driven by the drivingchain 43, the'discknives 3, 5, 45and 6, the conveyor 2, the driving wheel -23 of the belt '20 "and alsothe supplemental conveyor l6.

The entraihremoving members '7Jp'referably are formed 'attheir' endswith extracting *augers, ;preferably formed by twisted plates 50. Theseentrail'removing members are-provided with; first,'mea ns'for revolvingthe same in operation; second, means for advancing'and retracting samein and from "the visceral cavity of-the'fishto be cleaned;

third, with means formoving'the same=in gsynchronism with the motionofthe fi h holding conveyor 2, during that porti'o'n of "the/operationin'which they are acting upon "the fish supported by said conveyor-*2.

-As'b,est illustrated in'Figs. '5"and-6, the

"'entrail removing members 7 areipreferably supported in"tl1e"turret8,Wl11i0ll is formed by a spider 51 and a spider 52 at opposite ends, ofthe tiirret, "which-spiders 51 and 52 are fixed to the shaft 13u-p'on'which =is parallel to the shaft 1 13, which turret 5 rods mountedthe'rear'sprocket wheel 11 of the conveyor 12. The spiders 51 and 52 areconfront end of the carriers 54, there are pro-' vided sleeves 59 and 60on the shafts 57, and at the rear end of the carriers 54, there areprovided sleeves 61, and said sleeves are brought up tight by springs 62coiled around the shafts 57, between the auger heads and the sleeve 60of the entrail removing members. The sleeve 59 has a slight ly sphericalend where it engages the carriers 54. The construction thus described,

permits'the entrail removing members 7 or the auger heads to moveslightly in the apparatus in order that they may properly enter thevisceral cavity of the fish to be cleaned.

As-illustrated in Figure 11, the visceral cavity of a fish, such assardine, is located at one side of the center of the fish and if e theentrail removing members 7 were rigidend of a shaft 66.

ly mounted, it would require that the fish be always positioned at theholders 9 of the conveyor 2, with their visceral cavities al-- ways in apredetermined position. By providing a flexible mounting for the entrailremoving members 7, these members selfposition themselves within thevisceral cavities when they are advanced into the fish, as such cavitiesconstitute the point of least resistance in the fish.

The shafts 57 are shown as connected by universal connection 63 with asliding driving shaft 64 which is squared throughout the major portionand fits within the squared The shaft 66, at its rear end, mounts apinion 67 meshing with a gear 68 which is loosely journaled upon theshaft 13 and rigid with a sprocket wheel 69, having a chain drive from asprocket wheel 7 0 on the shaft 41 mounting the belt pulley 40. Theconstruction thus described provides a means by which the augers orentrail removing members 7 may be continuously rotated during operation.

The hollow shafts 66 are journaled in sleeves 71 and. the shaft 66 isprovided near its front end with a retaining ring 72 for retaining theshaft in fixed axial position with reference to the sleeve 71., As bestillustrated in Figures 6 and 8, the sleeves 71 have, near their ends,arms 73 which are pivoted to the turret rods 53, and the arms machine.

73 are yieldingly urged into position to press the pinions 67 againstthe gear wheel 68, by means which rods 74 and springs 75 are attached tothe spider 51.'

The carriers 54 for the entrail removing members 7 have tongues engagingwithin grooves upon a cylinder 76, fixed to the shaft 13 so thatthecarriers are provided with two points of support to prevent thecarriers being revolved on the turret rods 53. The carriers 54 upontheir outer ends, mount rollers 78 which work in' a cam-way of acylindrical cam 79 surrounding the turret and fixed to the frame 14.

As best illustrated in Figure 12, thecam 79 is constructed so that atabout 180 of the rotation of the entrail removing turret 8, the entrailremoving members 7 are in a:

retracted position, out of engagement with the fish in the conveyor2.The cam 79 then i i has a portion 80 operative for advancing thecarriers 54 and the entrail removing members 7 to a position where theentrail re moving members engage the ends of the fish within theconveyor 2. For about 45 of rotation of the turret 8, the entrailremoving members are held in this position of advance which provides atime in which the entrail removing members 7 may locate themselves withtheir ends in the visceral cavities of the fish. 1

A further development 81 of the cam surface then advances the entrailremoving members into the visceral cavities of the fish to the advancedposition indicated in' Figure 11, after which the cam surface is shapedto again retract the entrail removing members 7 to the retractedposition.

The front spider'52 of the-turret is indicated as built up of aplurality of sections 1 83 in addition to a hub 84, and'the sections 83of the front spider 52 are provided with lugs 85 in number equal to thenumber of rods36 in the rear belt 31 which holds the fish in theconveyor 2 during the entrail re-' moving operations. The lugs 85project into position to drive thebe'lt 31 by engagement with therods36, thus insuring that the motion of the belt 31 will be inaccurate'synchronism with the motion, bothof theconveyor 2 and the entrailremoving turret 8. There is also indicated a spray line 86, by means ofwhich water may be sprayed for cleaning the entrail removing members.

87 indicates grease cups for supplying lubricant to the sleeves 71.

In operation the fish are positioned within the receivers 9' of theconveyor 2 with their heads towards the turret end of the machinery, forexample, the feeding machine described in my Patent No. 1,614,588,issued J anuary18, 1927, may be employed, or the The fish may be fedeither by fish may be positioned by hand, in which case, it would bedesirable to lengthen somewhat, ;the forward end =of the conveyor inorder tOzPI'OVldGTOOIIl for operators.

As the fish pass between the two pairs ofcontinuously revolving knives3, 4: and 5, -6,;the headsand .tails of the fish are severed therefrom,z and the 7 fish: are i then continuously advanced to the "entrailremoving turret 8. .As the fish arrive at the entrail remov- 10 iingturret, the entrail =removing .member of .augers i first'advance untilthey arein engagement withthe ends ofthe fish at which time thecontinuously revolving angers seek their way into the visceralcavities'of the :fishiandf are then ffurther'advanced into saidcavities, during which time the entrails of the fish are removed by theangers. The angers Tare preferably rotated at; relatively ihigh speed to.Whirl'the entrails loose from the fish for withdrawal'of the, angersfrom the cavities.

Another :feature: of the present invention resides in the employment ofmeans for severing. theheads and-tails of the fish which 5" are of: an'improved form.

The present machine provides a pair of revolving 'discs havingoverlapping cutting edges-atthe point where the heads or the tailsaretobe severed .from'the fish and the cuttingdiscs-are revolved so thatthe cutting edges move with the direction of the -fish,removing theheads and-tails of the fish by a shearing action.

. In the gpreferred form of the machine,

the cuttingdiscs of eachpair revolve at different speeds, so as tocontinually present different-cutting edges *to each other which has theeffect ofn-iaintaining the discs sharp .and f-acilitatesthei cuttingaction.

:Also,':in:thepreferred form, ofthe machine one-of'theacutting discs,preferably u'ppe'rfisrotated so that its' cutting edge in contact withthe. fish is moving at:about the same speed as the fish, while thecutting .edgeof-theother discfis'revolving more rap- ':id1y.,This-action'is found .tolprevent'the fish from v being squeezed in thecutters in clitting operations, :andalso to result in a ivery cleanremovalzof. both the heads and 'tailszof the fish.v .In the prior formsof-fish cleaning'=machines, the fo-rmof-severing means usedhad Ea;tendencyrto crush the fish or-to merelytear. the head or the tail fromtheifish. r g

While the form of the invention described is well adapted tocarryoutthe-objects of .the presentfinventiorn'it is understood thatvarious modifications and changes may be made, all within the spirit ofthe invention nand theinvention includes allsuch modifiacationsa-ndichanges ascome within the scope *ofithei appended claims.
